Find the zeros of each function. f(x) = 6x^2 - 7x - 20

What are the values of each variable in the diagram below?

The point a is at –2 and the point b is at 7. marissa would like to divide this line segment in a 4: 3 ratio, and she would like to use the formula x = (x2 – x1) + x1. what values should she substitute into the formula? a = a + b = x1 = x2 =
